| Research Abstract |
Mossbauer spectroscopy is applied to the phosphinobrane gold(I) complex having Au→B interaction and stiborane bonded by AuL fragments to obtain experimental insights on the M→L bond. 197Au Mossbauer spectra suggest the weak Au→B interactions in diphosphinobrane complexes and no significant interaction in monophosphino complex. 121Sb Mossbauer spectrum clearly indicates the considerable electron density at Sb-Au bond in the equatorial plane of the stiborane. Crystal structure determination of a stiborane with Au(PPh3)2is also done.
